llvm dev - Apr 2013 - [LLVMdev] creating and inserting a function with variable arguments

I am working on a pass in which I need to define and insert a function with
variable arguments. Can I do it with the help of getOrInsertFunction()? If
not can someone tell me any other method?
It will be very helpful if anyone can help. Thanks in advance

Sure. There is an overload of getOrInsertFunction that takes a
FunctionType, and there are FunctionType::get static methods where you
say if the function type takes a variable number of arguments. See the
doxygen documentation for FunctionType and Module::getOrInsertFunction.

I have tried it, but I always end up with some kind of error. Can you
explain how can I get a function type for function which returns void
(nothing) and it's arguments are (int, int, int, void *, void *, ...) ??

Thanks in advance.
